Coming deliverance: God's own thoughts of grace

On the other hand the prophet comforts those who, by the
judgment of God, were subjected to the yoke which He had imposed
upon them. The Jews in Babylon should dwell in peace, quietly
seeking the welfare of the city in which they were captives. The
time of deliverance should come. The spirit of rebellion should be
punished. Finally, having insisted on the people's submission to
the judgment, God reveals His own thoughts of grace. This
submission was necessary, because of Israel's sin; for God must
maintain His own character, and not identify Himself with the ways
of a rebellious people. But He must needs manifest Himself as He is
in His grace. The execution of the judgment, and Israel's ruined
condition, brought the truth and beauty of the grace of God into
yet greater prominence.
